We mostly dry camp. For years I have been keeping the batteries charged by plugging in the trailer power cord to a small Honda or my new Yamaha 2000 watt generator. Trailer has a 7355 Parallax conver...

When the onboard charger slumps to 10 amperes, connect the manual charger and watch the amperage jump up. Where does some of this information come from? Jeez! That 8 amp charging port ROBS field excitation electricity from the generator rotor. Measure it open circuit. It will read something near EIGHTEEN VOLTS. My 5500 diesel Yamaha had a belt driven alternator I measured at at 21 amperes max at 14.1 volts regulated.
Robbing the field for battery charging can rob the generator A.C. output potential from say 3,000 watts to 800 watts. This is a fact of life with any home generator with a field voltage tap.
